Research direction
Start at com.microsoft.graph.core.tasks.PageIterator, especially extractEntityListFromParsable at PageIterator.java:300, and inspect the library's Android ProGuard configuration. Reproduce the minified DriveItem PageIterator example, then verify that a packaged rule preserves the response method and minified iteration succeeds.
Written by the indexing model from the issue text.
Description
Describe the bug
On Android with a minified build, an exception occurs with PageIterator over DriveItems. The PageIterator class calls getDeclaredMethod("getValue") on the response class. The response getValue method appears to be removed by the minified build.
Exception:
java.lang.IllegalAccessException: NO_COLLECTION_PROPERTY_ERROR
at com.microsoft.graph.core.tasks.PageIterator.extractEntityListFromParsable(PageIterator.java:300)
at com.microsoft.graph.core.tasks.PageIterator$Builder.build(PageIterator.java:203)
at com.microsoft.graph.core.tasks.PageIterator$Builder.build(PageIterator.java:210)
Expected behavior
Proguard rules provided by the library would include the needed classes/methods for PageIterator to work.
How to reproduce
Code:
var resp =
client.drives().byDriveId(driveId).items().byDriveItemId("root").children().get();
var pageIter =
new PageIterator.Builder<DriveItem, DriveItemCollectionResponse>()
.client(client)
.collectionPage(resp)
.collectionPageFactory(DriveItemCollectionResponse::createFromDiscriminatorValue)
.processPageItemCallback(item -> {
// use DriveItem item...
return true;
})
.build();
pageIter.iterate();
